Biography:

Dr. Scott Hensley received his BS degrees in mathematics and physics from the University of California at Irvine. He received a PhD in mathematics from the State University of New York at Stony Brook, where he specialized in the study of differential geometry. Subsequent to graduating, Dr. Hensley worked at Hughes Aircraft Company on a variety of radar systems, including the Magellan radar.

In 1992, Dr. Hensley joined the staff of the Jet Propulsion Laboratory, where he studies advanced radar techniques for geophysical applications. His research has involved using both stereo and interferometric data acquired by the Magellan spacecraft at Venus. Dr. Hensley has worked with ERS-1, JERS-1 and SIR-C data for differential interferometry studies of earthquakes and volcanoes. He was a major contributor to the ROI-PAC software package for processing radar differential interferometry data.

Current research also includes studying the amount of penetration into the vegetation canopy using simultaneous L- and C-band TOPSAR measurements and repeat-pass airborne interferometry data collected at lower frequencies (P-band). He was the Chief Scientist for GeoSAR, a simultaneous X-band and P-band radar interferometer for mapping above and beneath the canopy, which is now commercially operated by Earthdata International. He was the technical lead of the Interferometric Processor Development Team of the Shuttle Radar Topography Mission (SRTM), a shuttle-based interferometric radar used to map the Earth’s topography between ±60° latitude.

He is currently the principal investigator of NASA's UAVSAR program, which is developing a repeat-pass radar interferometry capability for use on conventional or uninhabited aerial vehicles. Recently, he began working with the Goldstone Solar System Radar to generate topographic maps of the lunar surface.
